The utility model discloses a foldable solar panel with a bistable characteristic. The solar panel comprises a solar panel main body and an antisymmetric bistable cylindrical shell, wherein the solarpanel main body comprises a central solar panel and side edge solar panels; four sides of the central solar panel are respectively connected with one side solar panel through an antisymmetric bistablecylindrical shell; the central solar panel and the side edge solar panels can rotate relatively, shape memory alloy is arranged on the outer side of the antisymmetric bistable cylindrical shell, andthe shape recovery direction of the shape memory alloy is consistent with the circumferential direction of the antisymmetric bistable cylindrical shell. The solar panel is simple in structure, convenient to use, good in stability, flexible, light in weight and small in size, replaces an unfolding structure of a traditional mechanical solar panel, and has a good application prospect. 本实用新型公开了一种具有双稳态特性可折叠的太阳能板，包括太阳能板主体和反对称双稳态
